The key danger for polar bears posed by the effects of climate change is malnutrition or starvation due to habitat loss.Polar bears hunt seals from a platform of sea ice. Rising temperatures cause the sea ice to melt earlier in the year, driving the bears to shore before they have built sufficient fat reserves to survive the period of scarce food in the late summer and early fall.
Thanks to climate change, polar bears are not getting enough to eat. Scientists from Washington State University and the U.S. Geological Survey equipped 20 polar bears in northern Canada with ...
Polar bears have been trained to perform in circuses. Bears in general, being large, powerful, easy to train and human-like in form, were widespread in circuses, and the white coat of polar bears made them particularly attractive. Circuses helped change the polar bear's image from a fearsome monster to something more comical.
Climate change can also be used more broadly to include changes to the climate that have happened throughout Earth's history. [32] Global warming—used as early as 1975 [33] —became the more popular term after NASA climate scientist James Hansen used it in his 1988 testimony in the U.S. Senate. [34] Since the 2000s, climate change has ...
As climate change diminishes sea ice from coastal communities in the Arctic and the subarctic, researchers expect polar bears to range farther into the towns
Glacier melt is forcing polar bears into the water where they must swim for days at a time to find solid ground. Climate change is forcing polar bears to swim for days on end to solid ground Skip ...
Seals are another marine mammal that are susceptible to climate change. [114] Much like polar bears, some seal species have evolved to rely on sea ice. They use the ice platforms for breeding and raising young seal pups.
One of the negative effects of climate change is the decline of polar bear populations. Taylor believes that "Polar bears, as a species, do not appear to be threatened or in decline based on the data that I’ve seen at the present time, although some populations do seem to be experiencing deleterious effects from climate change."
